A hemispherical bowl of internal diameter 36 cm is full of liquid. This liquid is to be filled into cylinderical bottles each of radius 3 cm and height 12 cm. How many such bottles are required to empty the bowl ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 ie 36.
Internal diameter = 36 cm
Radii = 18 cm
V = (2/3) π r³
π × (2/3) × 18³ = n × 3² × 12 × π
n = 18³ / (3³ × 6)
n = 36
